Can you just see a black hole in the lake? Unbelieavable! I don't really dare to get close to it... otherwise I might get sucked by the hole... fallen to under the sea! I still wondering where does this great hole leads to, like a great huge circle of fire in Darvaza, it leads to an underground cave. If you see it, don't get close when you are rowing in a boat near it, just keep rowing until you get further from it!
